Abstract
Abstract An arthroscopic method and apparatus for implanting a suture anchor into tissue using a cannulated tissue-shifting guide. Tissue at a repair site is secured with a cannulated tissue-shifting guide. Suture material is appended to a suture anchor. The suture anchor is attached to a device driver and installed through the cannulated tissue-shifting guide at the repair site and into bone. A power drill can be attached to the device driver and used to drive the suture anchor during installation.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
89 words
A method for installing a suture anchor for securing tissue to bone using a cannulated tissue-shifting guide having a tip, the method comprising the steps of: (a) contacting the tissue with the tip of the cannulated tissue-shifting guide; (b) introducing the suture anchor to the tissue through the cannulated tissue-shifting guide; (c) installing the suture anchor through the tissue and into the bone by rotating and advancing the suture anchor; and (d) removing the cannulated tissue-shifting guide from the repair site, leaving the suture anchor installed in the bone.
Claim 2
Independent Claim
89 words
A method for installing a suture anchor for securing tissue to bone using a cannulated tissue-shifting guide having a tip, the method comprising the steps of: (a) contacting the tissue with the tip of the cannulated tissue-shifting guide; (b) introducing the suture anchor to the tissue through the cannulated tissue-shifting guide; (c) installing the suture anchor through the tissue and into the bone by rotating and advancing the suture anchor; and (d) removing the cannulated tissue-shifting guide from the repair site, leaving the suture anchor installed in the bone.
Claim 3
Dependent Claim
28 words
The method of claim 1, wherein the step of installing the suture anchor comprises using a power drill to rotate and advance the suture anchor into the bone.
Claim 4
Dependent Claim
28 words
The method of claim 1, further comprising the step of threading the suture anchor with suture prior to the step of introducing the suture anchor to the tissue.
Claim 5
Dependent Claim
21 words
The method of claim 1, further comprising the step of delivering the cannulated tissue-shifting guide to the tissue through a portal.
Claim 6
Dependent Claim
36 words
The method of claim 1, wherein the step of contacting the tissue with the tip of the cannulated tissue-shifting guide comprises maneuvering the guide using a handle disposed on the proximal end of the cannulated guide.
Claim 7
Dependent Claim
38 words
The method of claim 1, wherein the tip of the cannulated tissue-shifting guide comprises a protrusion, and the step of contacting the tissue with the tip of the cannulated tissue-shifting guide comprises contacting the tissue with the protrusion.
Claim 8
Dependent Claim
33 words
The method of claim 6, wherein the protrusion is forked, and the step of contacting the tissue with the tip of the cannulated tissue-shifting guide comprises contacting the tissue with the forked protrusion.
Claim 9
Dependent Claim
55 words
The method of claim 1, wherein the cannulated guide further comprises an opening in a wall of the guide, and the step of introducing the suture anchor to the tissue through the cannulated tissue-shifting guide comprises viewing the suture anchor being passed through the cannulated tube through the opening in the wall of the guide.
Claim 10
Independent Claim
102 words
A method of installing a suture anchor into bone using a cannulated tissue-shifting guide having a tip, the suture anchor having a proximal end, the method comprising the steps of: (a) coupling the proximal end of the suture anchor to a device driver; (b) threading the suture from the suture anchor through the device driver; (c) inserting the device driver and the suture anchor through the cannulated tissue-shifting guide; (d) attaching a power drill to the proximal end of the device driver; and (e) installing the suture anchor into the bone using the power drill to rotate and advance the suture anchor.
Claim 11
Independent Claim
102 words
A method of installing a suture anchor into bone using a cannulated tissue-shifting guide having a tip, the suture anchor having a proximal end, the method comprising the steps of: (a) coupling the proximal end of the suture anchor to a device driver; (b) threading the suture from the suture anchor through the device driver; (c) inserting the device driver and the suture anchor through the cannulated tissue-shifting guide; (d) attaching a power drill to the proximal end of the device driver; and (e) installing the suture anchor into the bone using the power drill to rotate and advance the suture anchor.
Claim 12
Dependent Claim
30 words
The method of claim 9, further comprising the steps of: contacting the tissue with the tip of the cannulated tissue-shifting guide; and positioning the tissue with the cannulated tissue-shifting guide.
Claim 13
Dependent Claim
30 words
The method of claim 10, wherein the steps of contacting and positioning the tissue comprise maneuvering the tissue-shifting guide using a handle disposed on a proximal end of the guide.
